7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart approach to solve comfort issues in your house. These systems don’t require ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can run into issues sometimes. Here are seven of the most frequent mini-split problems and how you can fix them.

1. Mini-Split is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there may be a problem with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and drip. Call Hale's Air Conditioning Services Inc at 727-369-6195 for help and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re running. But there are a couple of times where they might produce sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can occur if your mini-split turns on defrost mode to keep itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re expected. However, if your mini-split keeps going into defrost mode, it’s a hint that something is off, including low refrigerant, a faulty circuit board or malfunctioning sensors. Your Hale's Air Conditioning Services Inc HVAC pro will be able to find and resolve the problem quickly.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, frozen coils might be the problem. Like we talked about previously, icy coils may be the effect of insufficient refrigerant, a bad circuit board or broken sensors. Reach us at 727-369-6195 for help.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC uses refrigerant to transfer heat and keep your residence cold. These leaks must be repaired by a licensed HVAC professional, so contact us at 727-369-6195 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this could be interrupted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s oversized. A system that’s oversized will cool down a space too rapidly without having time to dehumidify it. Mini-split size is calculated on square footage and BTUs.

6. Mini-Split Smells

If your ductless mini-split smells, it’s trying to get your attention that something is wrong. Here are five of the most common smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you may have a mold issue. Have a specialist like Hale's Air Conditioning Services Inc check and rinse the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely experiencing a refrigerant leak. Another certain clue that you don’t have enough refrigerant is a lack of cool air. Contact us at 727-369-6195 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Regardless, reach us at 727-369-6195 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are out of juice, your mini-split won’t run. In most situations, putting in fresh batteries will solve the problem. If you’re still experiencing trouble, reach us at 727-369-6195.
